Bearing Housing Casting

Roots Blower Bearing Housing by WALKSON

Function

The Roots Blower Bearing Housing Casting supports and aligns the bearings that facilitate rotor rotation within the blower. It maintains precise rotor positioning, absorbs operational stresses, and protects bearings from contaminants and excessive loads. By ensuring smooth and stable rotor operation, the bearing housing is essential for minimizing vibration, reducing wear, and extending the blower’s lifespan. Given its critical role in maintenance and repair, bearing housings are in high demand in industrial markets.

Specific Design

WALKSON’s bearing housings are engineered for precision and durability, featuring tight tolerances and robust construction to withstand high loads and harsh conditions. The design includes mounting surfaces for secure attachment to the blower’s end plates and precise bores for bearing installation, ensuring optimal alignment and performance. Custom configurations are available to match specific blower models or application needs, enhancing compatibility and functionality. The housings are designed to dissipate heat and resist corrosion, with reinforced structures for added strength. Advanced CAD modeling ensures a perfect fit and reliable operation.

Material Grades

WALKSON offers Roots Blower Bearing Housing Castings in high-quality materials compliant with international standards, selected for their strength, durability, and performance:

· Gray Iron: Conforms to ASTM A48 (e.g., Class 30, tensile strength 30,000 psi) and EN 1561 (e.g., EN-GJL-200). Gray iron provides excellent machinability, vibration damping, and cost-effectiveness, ideal for standard applications (ASTM A48, EN 1561).

· Ductile Iron: Meets ASTM A536 (e.g., 65-45-12, balancing strength and ductility) and EN 1563 (e.g., EN-GJS-400-15). Ductile iron offers superior toughness and wear resistance for high-load or abrasive environments (ASTM A536, EN 1563).

· Custom Alloys: Stainless steel or other specialized alloys are available for corrosive or high-temperature applications, tailored to client specifications.

Material selection is based on operational requirements, ensuring optimal performance and longevity.

Modern and Standardized Manufacturing Process

WALKSON employs a state-of-the-art manufacturing process to produce high-quality bearing housings:

· Pattern Making: Precision patterns are created using CAD and CNC machining for accurate mold formation.

· Casting: Sand casting is used for cost-effectiveness, while investment casting is employed for complex geometries requiring high precision.

· Machining: Advanced CNC machining centers ensure precise finishing, achieving tight tolerances and smooth surfaces for bearing alignment and mounting.

· Quality Control: Rigorous inspections at each stage, from material verification to final dimensional checks, ensure defect-free components.

The process is standardized to ensure consistency, repeatability, and compliance with customer specifications.
